WILLIAM F. STRAUB, OF CHICAGO, ILLINOIS, ASSIGNOR T ELECTRIC TIME RECORDER COMPANY, OF CHICAGO, ILLINOIS.

POCKET-SHIFT.

Application filed February 11, 1913.

To all whom it may, concern:

Be it known that I, lVILLnur STRAUB, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Pocket-Shifts, of which the following is a full, clear, concise. and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invent-ion relates to time recorder devices and more particularly to those devices in which a card or similar appliance may be mounted in place to receive an indication. These devices as is well understood are of use in connection with the time cards as stamped by employees in factories or similar places to indicate the time of enterthe establishment and leaving the establishment. The card is usually provided with various rows and the particular row in which the stamping indication is made serves to indicate entry or exit and also serves to indicate whether the stamping was done during the forenoon or afternoon; also may serve to indicate whether the indication was stamped as of such a time which would indicate overtime or other similar special feature, and is also so devised that the indications for each succeeding day are lower or higher on the card as the case may be with respect to the indications of the preceding day.

My invention contemplates the provision of means for setting certain mechanism associated with time recorders whereby the card when inserted by the employee automatically assumes the position which adapts it to receive the necessary time indication at that particular portion of the card allotted therefor for that particular condition.

I will explain one form which my invention may take by referring to the accompanying drawings illustrating said embodiment, in which- Figure 1 is a partial longitudinal. sec-' tional view of my improved device; Fig; 2 is a top view of the driving mechanism thereof; Fig. 3 is a partial rear view of some of the card; Fig. 4 is a front view of the device, certain portions thereof being broken away more clearly to reveal features of con struction; Fig. 5 is a top view of certain parts of the shifting mechanism; Figs. 6, 7 and 8 are detail views respectively of certain Specification of Letters Patent.

parts of the card position controlling mecha-- msm, and Fig. 9 is a view of the record card.

My improved time recorder consists of a rear lJOX portion 1 having a cover 2 hinged thereto, which cover carries at its front a box portion 3. The boX 3 has within its confines the actuating mechanism to actuate the type wheels to make an indication and the correlated parts. At the top of the structure a suitable dial st is provided having hands 5 and (i, which through the interposition of a crown gear 8 and other gear mechanism are driven by means of the shaft 9. to indicate the time. A chute 10 is provided which is adapted to receive the card (if such is used) upon which the indication is to be made. This chute 10 is designed to be shifted crosswise of the machine as will appear hereinafter, and below this chute certain instrumentalities in the nature of prongs or arms 1.1 project into a position so that the card inserted in the chute 10 may rest upon these arms 11. These arms are mounted on chains 12, which chains are carried about sheaves 13 fixedly mounted on shafts 14 and 15 respectively. Through the agency of the shaft 9 and worm 16 a worm wheel 17 loosely mounted on the shaft 1 1 is driven by means of which this shaft 9 periodically changes the position of the arms 11 to thereby change the depth to which the card inserted in the chute 10 may be admitted. The depth to which the card is admitted depends upon the day of the week and thus these arms 11 must be shifted once for each day. The shaft 9 through the interposition of suitable gearing 18 and 19 as more clearly set forth 1n my co-pending application Serial No. 735,?18, filed Dec. 9, 1912, (Case 7) is driven by means of three electromagnets 20, 21 and 22, which electromagnets are periodically energized in rotation to thereby occasion the progressive step-by-step rotary movement of an armature 23, which armature has prongs 2 f as more clearly shown in Fig. 2.

It will be seen that as the electromagnets 20, 21 and 22 are energized in rotation, the particular magnet energized attracts the nearest prong 2% whereby the armature 23 is thus rotated. This armature carries and is fastened to the gear 19 to thereby drive the shaft 9. The gear 19 also meshes with a pin 25 by means of which a shaft 26 is rotated to set by means of the bevel gears 27 and 28 the stamp wheels 29. These stamp wheels are suitably actuated through the agency of the lever 30 all as more clearly explained and set forth in my said co-pending application. The chute 10 of course holds the card in position so that the stamp wheels may make an indication thereon whenever properly actuated.

In order to effect a movement of the chains 12, a certain predetermined distance once for each day, the mechanism shown more clearly in Figs. 3, 6, 7 and 8 is employed. This mechanism is of such a character that the movement of the chains 12 is not gradual but is effected practically instantaneously once during each day or once during any other predetermined interval of time that may be selected. The worm wheel 17 is provided with a pin 31 which enters agroove 32 in the shaft 14 so that this worm wheel may rotate about the said shaft 14 but retain its longitudinal alinement. A sleeve 32 is also loosely mounted upon the shaft 14 and has a disk 33 fixedly associated with a plate 34 and having a single indentation 35 for the purpose of actuating a pinion 36 once during each revolution of the element 34 as will presently appear.

. This sleeve 32 is adapted for screw threaded engagement with the worm wheel 17. VVithin the sleeve 32 is loosely mounted the element 37 between which elements 37 and 32 a spring 38 is fastened, one extremity being fastened to the element 32 and the other extremity to the element 37. The worm wheel has two springs 39, 39 which are fastened to the worm wheel and which have pins 40 adapted to enter the apertures 41 provided in the element 37. Thus whenever the worm wheel 17 turns it carries with it by means of the spring pins 40 engaging holes 41, the element 37 and assuming that the sleeve 32 is stationary, this rotation of the worm wheel 17 will wind up the spring 38. At the same time that it winds up the spring 38 this movement of the worm wheel pushes the elements 32, 33, 34, 37 and 38 to the left through its engagement with the threaded sleeve 32 (Fig. 7) for purposes that will presently appear. The element 32 has an integral annular cylindrical portion 42 which carries a projection 43 which normally abuts a projection 44 rigidly secured to the framework of the machine at 45, as will be clear from Fig. 6.

The gear wheel 36 has throughout the left hand portion of its periphery as at 46 six teeth and at the right hand portion of its periphery as at 47 only three, teeth. This pinion 36 drives a gear wheel 48 integrally fastened to the left hand sheave 13 secured to the shaft 14. Now during the rotation of the shaft 9 the worm wheel 17 is continuously rotated, thereby winding up the spring 38 and moving the elements 32 and associated parts to the left until such a time as the projection is disengaged from the projection 44, atwhich time the spring 38 is released. It has been assumed that the worm wheel 17 is rotating clockwise. Now the minute the projection 43 has been moved to the left substantially to disengage itself from the projection 44, the spring 38 by reason of beingwound up rotates the element 32 and associated parts therewith clockwise one revolution during which revolution these elements again move toward the right by virtue of thescrew threaded connection between these elements and the worm wheel 17, and at the end of this one revolution the projection 43 is again abutting the projection 44. During this one revolution the element 33 has engaged one of the teeth of the pinion 36 and rotated the pinion 36 the distance of one tooth, thereby moving the chains 11 the required unit distance.

It will be understood of course that the element 34 has two teeth 49 and 50 so that the first tooth 49 during the rotation of the element 34 may start the pinion in motion by engaging one of the siX teeth of the pinion 36, whereas the rounded surface of the element 33 by always resting in the space between two of the teeth of that portion of the pinionhaving but three teeth, prevents the rotation of this pinion a distance of more than one tooth, which might occur dueto the rapid motion of the elements 33 and 34 should no such provision be made. It will thus be seen that automatic mechanismvperiodically shifts the chains 12 whichautomatically recoils to set itself in position for a further actuation.

Now in order to shift the chute 10 from side to side I provide a rack 51 upon this chute, which rack engages a gear wheel 52, which gear wheel has several slots 53, 54 and 55. An arm 56 passes through the box portion 3 and has thumb pieces 57, 58 at its opposite extremities. A spring 59 tends to rotate this shaft 56 contra clockwise looking at the device from the left, Fig. 5. This shaft 56 is provided with a cam 60, which cam through the interposition of a suitable roller,61 and spring 62 moves it into its limiting position either to theright or to the left. The shaft 56 carries an arm 63 7 of the chute 10 is secured so that moving it to the right will give the entrance indication and moyingitto the left may give the exit indication as is customary. By this it is meant that when the shaft is in the position shown all indications made would record an entrance of the employee, whereas if the shaft 56 were in its alternative position to the right, the exit of the employee would be on record.

From what has been described it will be readily apparent that my improved apparatus serves the necessary setting functions for the card and also the manner in which this apparatus is driven. It will of course be apparent that many modifications may be made from the specific structure herein disclosed, but it is thought the spirit of the invention will be readily deducible from the foregoing.
